DETAILED DESCRIPTION

An image capturing lens assembly includes, in order from an object sideto an image side, a first lens element, a second lens element, a thirdlens element, a fourth lens element and a fifth lens element. The imagecapturing lens assembly has a total of five lens elements withrefractive power.

There is an air space between any two lens elements of the first lenselement, the second lens element, the third lens element, the fourthlens element and the fifth lens element adjacent to each other. That is,each of the first through fifth lens elements is a single andnon-cemented lens element, any two lens elements adjacent to each otherare not cemented, and there is a space between the two lens elements. Inother words, of the first lens element, the second lens element, thethird lens element, the fourth lens element and the fifth lens elementof the image capturing lens assembly, there is a space in a paraxialregion between any two lens elements that are adjacent to each other.Moreover, the manufacturing process of the cemented lenses is morecomplex than the non-cemented lenses. In particular, a second surface ofone lens element and a first surface of the following lens element needto have accurate curvature to ensure these two lens elements will behighly cemented. However, during the cementing process, those two lenselements might not be highly cemented due to displacement and it isthereby not favorable for the image quality of the image capturing lensassembly. Therefore, according to the image capturing lens assembly ofthe present disclosure, an air space in a paraxial region between anytwo of the first lens element, the second lens element, the third lenselement, the fourth lens element and the fifth lens element that areadjacent to each other improves the problem generated by the cementedlens elements.

The first lens element with positive refractive power has a convexobject-side surface, and can have a convex image-side surface.Therefore, the light converging ability of the image capturing lensassembly can be concentrated at the object side, which is favorable forcontrolling the size of the image capturing lens assembly for enhancingportability.

The second lens element can have negative refractive power. Therefore,the aberration of the image capturing lens assembly can be corrected soas to improve the image quality.

The third lens element can have positive refractive power and a conveximage-side surface. Therefore, the distribution of the positiverefractive power of the image capturing lens assembly can be balanced soas to reduce the sensitivity of refractive power distribution thereof.

The fourth lens element with negative refractive power can have aconcave object-side surface and a concave image-side surface. Therefore,the principal point of the image capturing lens assembly can bepositioned away from the image side so as to effectively control theback focal length, and the compact size can be maintained. Furthermore,the aberration of the image capturing lens assembly can be effectivelycorrected so as to improve the image quality.

The fifth lens element with negative refractive power can have a concaveobject-side surface and a convex image-side surface. Therefore, theprincipal point of the image capturing lens assembly can be positionedaway from the image side so as to effectively control the back focallength, and the compact size can be maintained. Furthermore, theastigmatism of the image capturing lens assembly can be effectivelycorrected so as to improve the image quality.

When a focal length of the image capturing lens assembly is f, acurvature radius of the object-side surface of the first lens element isR1, a curvature radius of the image-side surface of the first lenselement is R2, and a central thickness of the first lens element is CT1,the following relationship is satisfied:3.4<(f/R1)−(f/R2)+((f×CT1)/(R1×R2))<7.5. Therefore, the relationshipbetween the entire image capturing lens assembly and the surface shapeand thickness of the first lens element can be balanced, and apreferable effect can be provided by the first lens element. Thus, thephotographing range can be controlled so as to obtain a satisfying imagequality of the long-shot. Preferably, the following relationship can besatisfied: 3.7<(f/R1)−(f/R2)+((f×CT1)/(R1×R2))<6.0.

When a focal length of the first lens element is f1, and a focal lengthof the fourth lens element is f4, the following relationship issatisfied: −1.0<f1/f4<0. Therefore, the degree of light deflection atthe object side of the image capturing lens assembly can be enhanced,which enhances the magnification of the image capturing lens assemblywithin a limited space, and more light rays are received in the sameimage range.

When the focal length of the image capturing lens assembly is f, and thecurvature radius of the object-side surface of the first lens element isR1, the following relationship is satisfied: 3.4<f/R1. Therefore, thephotographing range can be effectively controlled, so that the imagequality of a portion of the image is featured with a higher resolution.

The image capturing lens assembly can further include a stop, such as anaperture stop. The stop is disposed between the first lens element andthe third lens element. When an axial distance between the stop and theimage-side surface of the fifth lens element is SD, and an axialdistance between the object-side surface of the first lens element andthe image-side surface of the fifth lens element is TD, the followingrelationship can be satisfied: 0.65<SD/TD<1.0. Therefore, thetelecentricity and the wide-angle character of the image capturing lensassembly can be balanced. Preferably, the following relationship can besatisfied: 0.65<SD/TD<0.87.

When a curvature radius of the image-side surface of the fourth lenselement is R8, and a curvature radius of the object-side surface of thefifth lens element is R9, the following relationship can be satisfied:−0.1<(R8+R9)/(R8−R9). Therefore, the air space between the fourth lenselement and the fifth lens element can be controlled so as to controlthe degree of light deflection between the fourth lens element and thefifth lens element, and the light converging ability at the paraxialfield and the off-axis field can be balanced.

When the curvature radius of the object-side surface of the first lenselement is R1, and the curvature radius of the image-side surface of thefirst lens element is R2, the following relationship can be satisfied:−1.5<(R1+R2)/(R1−R2)<0. Therefore, the generation of the aberration andthe astigmatism can be reduced, and the photographing range can becontrolled so as to obtain a satisfying image quality of the long-shot.

When a refractive index of the first lens element is N1, a refractiveindex of the second lens element is N2, a refractive index of the thirdlens element is N3, a refractive index of the fourth lens element is N4,a refractive index of the fifth lens element is N5, and a maximum of N1,N2, N3, N4 and N5 is Nmax, the following relationship can be satisfied:1.50<Nmax<1.70. Therefore, the configuration of the refractive index isproper for reducing the chromatic aberration, and the image quality canbe enhanced.

At least one lens element of the first lens element, the second lenselement, the third lens element, the fourth lens element and the fifthlens element can have positive refractive power, and an Abbe number ofthe lens element with positive refractive power is less than 30.Therefore, the distribution of the positive refractive power of theimage capturing lens assembly can be balanced, so that the sensitivityof refractive power distribution can be reduced, and the chromaticaberration can be corrected.

When an axial distance between the first lens element and the secondlens element is T12, an axial distance between the second lens elementand the third lens element is T23, an axial distance between the thirdlens element and the fourth lens element is T34, and an axial distancebetween the fourth lens element and the fifth lens element is T45, T45can be greater than T12, T23 and T34. Therefore, the space in the imagecapturing lens assembly is sufficient for controlling optical paths ofthe light rays entering into the image capturing lens assembly, and theimage height can be increased.

When the focal length of the image capturing lens assembly is f, and amaximum image height of the image capturing lens assembly is ImgH, thefollowing relationship can be satisfied: 2.3<f/ImgH<6.0. Therefore, thesize of the image capturing lens assembly can be effectively controlledso as to maintain the compact size, and the portability can be enhanced.

When an entrance pupil diameter of the image capturing lens assembly isEPD, and the maximum image height of the image capturing lens assemblyis ImgH, the following relationship can be satisfied: 0.7<EPD/ImgH<2.0.Therefore, the light rays entering into the image capturing lensassembly can be increased so as to obtain a higher resolving power.

At least one of the first lens element, the second lens element, thethird lens element, the fourth lens element and the fifth lens elementcan have at least one inflection point, so that the aberration of theoff-axis field can be corrected, and the image quality at the peripheryof the image can be improved.

When the focal length of the image capturing lens assembly is f, and anaxial distance between the object-side surface of the first lens elementand an image surface is TL, the following relationship can be satisfied:0.75<TL/f<1.0. Therefore, the space allocation for the lens elements ofthe image capturing lens assembly can be effectively controlled, and thelong-shot ability can be enhanced.

When the axial distance between the object-side surface of the firstlens element and the image surface is TL, the following relationship canbe satisfied: TL<7.5 mm. Therefore, the compact size of the imagecapturing lens assembly can be maintained.

The refractive power of the first lens element is stronger than therefractive power of the second lens element, the third lens element, thefourth lens element and the fifth lens element. (The result is obtainedfrom comparing the absolute values of the refractive power of the firstlens element, the second lens element, the third lens element, thefourth lens element and the fifth lens element. When the refractivepower is stronger, the absolute value of the refractive power is larger.Similarly, when the refractive power is weaker, the absolute value ofthe refractive power is smaller.) Therefore, the light convergingability of the first lens element can be enhanced, and the total tracklength of the image capturing lens assembly can be reduced.

When the focal length of the fourth lens element is f4, and a focallength of the fifth lens element is f5, the following relationship canbe satisfied: 0<f4/f5. Therefore, the principal point of the imagecapturing lens assembly can be positioned away from the image side so asto effectively control the back focal length, and the compact size canbe maintained.

When the axial distance between the third lens element and the fourthlens element is T34, and the axial distance between the fourth lenselement and the fifth lens element is T45, the following relationshipcan be satisfied: T34/T45<1.2. Therefore, the third lens element and thefourth lens element can be disposed more tightly for mutuallyeliminating the aberration while maintaining a sufficient space betweenthe fourth lens element and the fifth lens element.

When the axial distance between the object-side surface of the firstlens element and the image surface is TL, and the maximum image heightof the image capturing lens assembly is ImgH, the following relationshipcan be satisfied: 2.0<TL/ImgH<3.5. Therefore, the total track length ofthe image capturing lens assembly can be reduced, and the compact sizethereof can be maintained.

When an Abbe number of the fourth lens element is V4, and an Abbe numberof the fifth lens element is V5, the following relationship can besatisfied: 90<V4+V5<130. Therefore, the chromatic aberration of theimage capturing lens assembly can be corrected.

When a half of a maximal field of view of the image capturing lensassembly is HFOV, the following relationship can be satisfied:0.3<tan(2×HFOV)<1.1. Therefore, the field of view and the imaging rangeare proper, and the stray light rays can be reduced.

When a composite focal length of the first lens element and the secondlens element is f12, and a composite focal length of the fourth lenselement and the fifth lens element is f45, the following relationshipcan be satisfied: −2.0<f12/f45<0. Therefore, it is favorable for forminga telephoto optical system having positive refractive near the objectside and negative refractive near the image side, and a long-shot scenecan be clearly imaged on the image surface.

According to the image capturing lens assembly of the presentdisclosure, the lens elements thereof can be made of glass or plasticmaterial. When the lens elements are made of plastic material, themanufacturing cost can be effectively reduced. When the lens elementsare made of glass material, the distribution of the refractive powers ofthe image capturing lens assembly may be more flexible to design.Furthermore, surfaces of each lens element can be arranged to beaspheric (ASP), since the aspheric surface of the lens element is easyto form a shape other than spherical surface so as to have morecontrollable variables for eliminating the aberration thereof, and tofurther decrease the required number of the lens elements. Therefore,the total track length of the image capturing lens assembly can also bereduced.

According to the image capturing lens assembly of the presentdisclosure, each of an object-side surface and an image-side surface hasa paraxial region and an off-axis region. The paraxial region refers tothe region of the surface where light rays travel close to the opticalaxis, and the off-axis region refers to the region of the surface awayfrom the paraxial region. Particularly, if not stated otherwise, whenthe lens element has a convex surface, it indicates that the surface isconvex in the paraxial region thereof; when the lens element has aconcave surface, it indicates that the surface is concave in theparaxial region thereof. According to the image capturing lens assemblyof the present disclosure, the positive refractive power or the negativerefractive power of a lens element or the focal length of the lenselement, that is, refers to the refractive power or the focal length inthe paraxial region of the lens element.

According to the image capturing lens assembly of the presentdisclosure, the image surface of the image capturing lens assembly,based on the corresponding image sensor, can be flat or curved. Inparticular, the image surface can be a curved surface being concavefacing towards the object side.

According to the image capturing lens assembly of the presentdisclosure, the image capturing lens assembly can include at least onestop, such as an aperture stop, a glare stop or a field stop. Said glarestop or said field stop is for eliminating the stray light and therebyimproving the image resolution thereof.

According to the image capturing lens assembly of the presentdisclosure, an aperture stop can be configured as a front stop or amiddle stop. The front stop disposed between an imaged object and thefirst lens element can provide a longer distance between an exit pupilof the image capturing lens assembly and the image surface and therebyimproves the image-sensing efficiency of an image sensor. A middle stopdisposed between the first lens element and the image surface isfavorable for enlarging the field of view of the image capturing lensassembly and thereby provides a wider field of view for the same.

According to the image capturing lens assembly of the presentdisclosure, the image capturing lens assembly can be optionally appliedto moving focus optical systems, and is featured with good ability forcorrecting aberration and high image quality. The image capturing lensassembly of the present disclosure also can be applied to 3D(three-dimensional) image capturing applications, in products such asdigital cameras, mobile devices, digital tablets, smart TV, internetmonitoring device, game consoles with motion sensing function, drivingrecording systems, rear view camera systems, and wearable devices.

In theimage capturing device, the first lens element has positive refractivepower, so that the light converging ability of the image capturing lensassembly can be concentrated at the object side, which is favorable forcontrolling the size of the image capturing lens assembly for enhancingportability. Furthermore, both of the fourth lens element and the fifthlens element have negative refractive power, so that the principal pointof the image capturing lens assembly can be positioned away from theimage side thereof so as to effectively control the back focal length,and the compact size can be maintained. Preferably, the image capturingdevice can further include a barrel member, a holding member or acombination thereof.

The image capturing device can further include a prism disposed at anoptical path between an object and the image surface of the imagecapturing lens assembly. That is, the prism can be disposed between theobject and the image capturing lens assembly (as shown in FIG. 28),disposed inside the image capturing lens assembly (not shown), ordisposed between the image capturing lens assembly and the image surface(not shown). Therefore, the direction of the incident light rays can bechanged by the prism according practical needs, and the demanded heightof the image capturing lens assembly can be reduced. Accordingly, it isfavorable for maintaining the compact size of the image capturing deviceor an electronic device equipped with the image capturing device.

According to the present disclosure, an electronic device is provided.The electronic device includes the aforementioned image capturingdevice. Therefore, the image quality of the long-shot can be improvedwhile maintaining the compact size of the electronic device.
